Question

Leon has a container filled with 450 grams of tea leaves. Each morning, he uses 3 grams to make a cup of tea. Which expression can be used to represent the amount of tea leaves remaining after x days? plz help i have 2 minutes till it should be complete

Answer 1

`f(x)=450-3x.`

Explanation:

If Leon starts with 450 grams of tea leaves, and each morning he uses 3 grams of tea leaves, and if he uses this amount everyday then after
`x` days he will have used
`3x` grams of trees, and the grams of tea leaves
`f(x)` left will be

`\boxed{f(x)=450-3x}`

This equation simply means that the amount of tea leaves left
`f(x)` after
`x` days is equal to the initial amount of leaves (450 grams) minus the amount used in
`x` days
`(3x).`
